[0014] 2. In the present invention, the first fixing frame is fixed to the fixed end of the hydraulic rod, and the second fixing frame is fixed to the output end of the hydraulic rod. The cooperation between the first fixing frame and the bracket can increase the structural stability of the hydraulic rod. At the same time, the output end of the hydraulic rod can be limited by the second fixing frame, thereby increasing the stability of the hydraulic rod during output. A buffering force can be given to the telescopic rod by the spring, one end of the spring is fixed to one side of the connecting frame, and the other end of the spring is fixed to the fixed end of the telescopic rod, so that the telescopic rod has a certain buffering effect when telescoping, preventing the bearing body from being suddenly clamped and damaged. The cooperation between the limiting rod and the slide plate can make the structure of the arc clamp block more stable, and it is also convenient to replace the arc clamp block with different curvature models to facilitate the curvature of the arc clamp block to be incompatible with the bearing body.

[0028] Through the above embodiment, the clamping rod 28 is driven to move toward the bearing body 1 by the hydraulic rod 22, the telescopic rod 25 and the connecting frame 27, and the bearing body 1 is limited by the arc clamping block 212, so that the bearing body 1 can be clamped and fixed. When the bearing body 1 needs to be adjusted, the clamping rod 28 is driven away from the bearing body 1 by the hydraulic rod 22, and then the rotating rod 297 is driven to rotate by the servo motor 298, the first shaft 299, the second shaft 2910, the first gear 2911, the first chain 2912, the third shaft 2913, the second gear 2914 and the second chain 2915, and the rotating rod 297 is Due to the action of the torsion spring 294, the rotating rod 297 will be tightly attached to the outer surface of the bearing body 1.

At this time, the bearing body 1 can be processed. When the processing position of the bearing body 1 needs to be changed, the hydraulic rod 22 is contracted to drive the clamping rod 28 to move five millimeters away from the bearing body 1. At this time, the bearing body 1 will be clamped by the rotating rod 297 and the arc clamping block 212. At this time, the servo motor 298 drives the rotating rod 297 to move, and the movement of the rotating rod 297 drives the bearing body 1 to move. At this time, the processing position of the bearing body 1 can be adjusted, and then the hydraulic rod 22 drives the clamping rod 28 to clamp and fix the bearing body 1 to continue processing.
